iOS (Jailbroken) Having your newly-taken photos automatically sync from your iPhone to iCloud with iOS 5 is convenient, for backup reasons, but did you know that this includes screenshots as well? If you don't want you screenshots to get mixed up with your actual photos, there's Screenshot Dam for jailbroken iOS devices.

You get this Cydia tweak the same way you get other Cydia tweaks: Search Cydia for the name "Screenshot Dam," then install it. You'll have to have your iOS device jailbroken, of course, but if you take a lot of screenshots and don't want them cluttering up your iCloud storage space, it's a good solution.
